How can I debug a buffer overflow in my C program?

To debug a buffer overflow, you can use tools like Valgrind or AddressSanitizer. Have you tried any of these?

I haven't used Valgrind before. How do I set it up?

You can install Valgrind using your package manager. For example, on Ubuntu, use sudo apt install valgrind. Then run your program with valgrind ./your_program.

What kind of output should I expect from Valgrind?

Valgrind will show you memory leaks, invalid reads/writes, and buffer overflows. Look for messages indicating 'Invalid write' or 'Invalid read'.

Thanks! Are there any common mistakes that lead to buffer overflows?

Yes, common mistakes include not checking array bounds, using unsafe functions like strcpy, and not allocating enough memory.
